The message specialpages-note-cached is used in EnhancedStandardUIs, even though it was deleted from core

Describe the issue / Steps to reproduce:
My colleague Tolu and I were cleaning up the list of translatable messages in core MediaWiki, and noticed that the message specialpages-note-cached is not used anywhere in core MediaWiki, but it is used in the EnhancedStandardUIs extension.

This message was recently removed from core: https://gerrit.wikimedia.org/r/c/mediawiki/core/+/1141454

I’m not a BlueSpice user, and I don’t know if it causes any actual problems, but I suspect that it might cause some issues. I recommend examining the usage of this message and updating it to the new core version.

Expected behavior:
The message specialpages-note-cached probably shouldn’t appear in the code of the EnhancedStandardUIs extension, unless it appears in its own en.json file.

What was the error message/error log?
No error message. I’ve just found it in codesearch.

System info:
Just the current version of EnhancedStandardUIs in Gerrit.

Hello and thanks for reaching out!

You are right, this particular code needs to be updated in master branch. In general, BlueSpice is being build on the MediaWiki LTS (1.43), which still contains that key. But in future releases this may be an issue. I will create a ticket to fix that.

Thanks again.
